Despite setting the 'required' attribute on the input tag and implementing an onclick form validation function to prevent empty strings, I am still experiencing issues where the page redirects to the next page with an empty string. It seems that there is a pre-fetched value being selected invisibly, causing this redirection. How can I completely clear this pre-fetched value from the input box when clearing the textbox? Any help would be greatly appreciated.

if (docName.trim() !== '') {
submitForm();
}
